java.util.ArrayList cannot be cast to [Ljava.util.ArrayList in hive

  Object values[] = (Object[])str.getValue();  // Target values

I changed above line to below and its giving this error

 ArrayList<Object> values[] = (ArrayList<Object>[])str.getValue();


Failed with exception
java.io.IOException:org.apache.hadoop.hive.ql.metadata.HiveException:
java.lang.ClassCastException: java.util.ArrayList cannot be cast to
[Ljava.util.ArrayList;
